Generally my deadlift day, I start with deadlifts off the floor. Don't really follow a set and rep program. Just go by feel, if my warmups are moving well I go heavy. If I'm not feeling it, I dial it back a bit and go for reps. Pretty much always to or near failure. Then do some RDLs for reps and move on to some back work.

I'm making good progress, before I could get 675 on my best day and now I'm regularly hitting it for 2-3 reps when I go heavy.

My lockout is the strongest portion of my lift. Usually if I can break it off the ground, I can lock it out. Debating trying to work some deficit deadlifts in but not really sure how to program it. Maybe start with deficits and do heavy then do competition deadlifts for my second movement in place of rdl? Or just start with comp deadlifts and then do deficits second? Want to see if it gets me stronger off the floor.

Not a fan of deficits because of my chit ankle mobility but you could try halting deadlifts.

670x3 is strong af. Im like 200lbs below that.

Personally, I wouldn’t do them on the same day. But I’m old, natty and have a fake hip. I still deadlift and squat though. And i’m shot after doing conventional deads. I wouldn’t do RDLs on the same day either. But that’s me.
Start light, the extra depth is awkward, at first. A que I use is to think about shoving my gut between my thighs.

Yeah for sure. When I do rdl it's cause I work up to a single heavy working set off the floor (1-5 reps) then do a set of rdl to failure after. At this point if I cut volume I go backwards. I think if I were to do deficits I'd still want to include at least some competition pulls just to keep that movement pattern fresh in my muscle memory.

I remember asking you at one time if you did them in your program because I remember you wanting to increase your deadlift. You want to do them on a separate day and perform early in your workout as your main strength exercise. You want to use a weight between 65-80% of your 1RM deadlift. It's a good starting point. 3-4 sets of 3-6 reps work well.

I would do them once a week on my back day...worked well for me.

Good luck!

Good Input. I've seen a couple different ways to do them. I've seen where people sink their hips to use more leg drive off the floor. Their hip hinges roughly the same angle as a normal deadlift.

I've also seen where people keep their hips in a similar start position as a normal deadlift but have a more severe hip hinge angle so their back is engaging more in the pull.

Because I want to focus more on floor strength I imagine I would want to sink my hips to focus on leg drive?

Probably a good reason for you to do them. Even 1 or two inch deficit. If it changes your form significantly then you either aren't pulling off the floor with optimal form or you are but are at a decent risk of injury relying on a stretch to get you in to position (been there).

As for OP. With what you can already pull I'd guess your form/position is pretty good already. I pull in low 600s and haven't found any use for them. RDL on the other hand have a near 100% carryover for me ie: if I can add 5 lbs to them I get 5 lbs on my DL. Basically the close grip benchpress of DL. Plus it gives your CNS a break.

Granted I've recently noted proportionately weak quads so maybe I'm such a posterior dominant puller (even more than usual in DL) that it explains why RDLs work so well.
